The Pros and Cons of Top 3 Biometric Verification Technologies

While biometric verification technologies are increasingly being integrated into our lives, it is important to be aware of the ones that offer the highest level of security.

From the day biometric verification was introduced in smartphones as a security method, this technology became an important part of our everyday life. In an attempt to make our lives more secure and convenient, new biometric authentications are emerging with every passing year. 

The uses of biometric verification are not confined to just smartphones. The technology is now used in numerous industry sectors as a mechanism for managing control, identifying criminals, suspicious activities, enabling services, and keeping the borders secure. The strength of biometric verification systems lies in their ability to eliminate the need to remember a password. Given its strengths, let’s take a look at the top three biometric authentication technologies and how they bring ease into our lives. 

What is Biometrics?

Biometrics is a method of identity verification that utilizes an individual’s physical characteristics. During this process, it is analyzed whether the person is actually who they claim to be. This makes the process less error-prone and highly difficult for imposters and fraudsters to replicate. 

Once an individual’s biometric data has been captured, it is cross-matched against a database of known biometrics. Biometric verification systems include facial recognition systems, fingerprint scanners, iris scanners, voice recognition, behavioral characteristics, and many more. However, among these, three biometrics are most common worldwide. Let’s go through them one by one. 

1. Facial Recognition Systems

Facial recognition is deemed as a rapid and easy-to-use method of biometric verification for customers and businesses alike. The technology has been introduced in the latest smartphones as well, apart from being used at airports and borders for managing access control and security. 

The process works by analyzing the unique features and characteristics on the end-user’s face. This can include the length of the nose, the width of the face, length of the forehead, contour of the lips, and so on. To make the method even more credible, it is often used along with other security methods, such as two-factor authentication. 

- The Strengths

  • Higher rate of acceptance than fingerprints

  • Frictionless method

  • Rapid results

  • Has a wide array of industrial applications

- The Weaknesses

  • If the camera or lighting placement is not accurate, verification does not take place

2. Iris Recognition

Iris recognition is another example of contactless verification that is gaining prominence worldwide. In this type of biometric verification, the technology uses the unique patterns found in an individual’s iris to identify them accurately. Since an iris is virtually impossible to reproduce, it is regarded as one of the most secure forms of verification methods. Some industries that commonly use iris recognition for enhancing security protocols include financial institutions, healthcare firms, schools and universities, and corporate offices. 

- The Strengths

  • Enables contactless verification 

  • Is not affected by different lighting conditions 

  • Swift and highly accurate verification results

- The Weaknesses

  • Can cause inconvenience for individuals that wear glasses 

  • Can only verify end-users from a certain distance 

  • Not very affecting for solving criminal investigations

3. Fingerprint Recognition

The most renowned of all biometric verification technologies is Fingerprint recognition. This method has long been utilized by businesses and was the first biometric authentication method that was introduced into smartphones. Apart from being introduced into smartphones, the technique is also considered a credible method for enhancing border protection. Law enforcement agencies have also been utilizing fingerprint scanning to ensure public safety. 

Instead of utilizing traditional capacitative sensors, fingerprint recognition now uses ultrasonic fingerprint ID to verify end-users. This allows companies to offer a higher level of security and cuts down the opportunity for hackers and fraudsters to manipulate the system using 3-D spoof techniques. 

- The Strengths

  • The results are highly accurate

  • Uses unique whorls and patterns for identity verification

  • Can be easily integrated with third-party devices

  • Enables database searching

  • Can be used through mobile applications by the police to identify known criminals

- The Weaknesses

  • This biometric verification method requires contact, hence cannot verify end-users from a distance

  • For individuals that wear gloves, the method can prove to be inconvenient

Key Takeaways

  • Biometric verification technologies are commonly used for managing access control, payment disbursement, and automating security checks at airports

  • Examples include fingerprint recognition, iris recognition, face detection systems, voice recognition, and more

  • While fingerprint recognition is highly convenient, it requires contact with users. Hence, it lags behind iris and facial recognition systems
